When processing specially crafted Code 128 input, decode_e() can return -1 for an invalid edge pattern, and decode6() subsequently left-shifts this negative signed value while constructing the edge signature. The operation invokes undefined behavior and can terminate trap-mode UBSan builds with SIGILL, resulting in denial of service.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://github.com/mchehab/zbar/issues/336","tags":[]}],"exploitRefs":[{"url":"https://github.com/mchehab/zbar/issues/336","tags":[]}],"hasPoc":true,"ai":null}
